Keycloak provides a way to manage identity providers and organizations through its administrative API. A flaw was discovered where an administrator with permission to manage identity providers could link a new provider to an organization without having the required permissions to manage that organization. This could allow an unauthorized administrator to influence how users log into specific organizations.

Keycloak provides a way to manage identity providers and organizations through its administrative API. A flaw was discovered where an administrator with permission to manage identity providers could link a new provider to an organization without having the required permissions to manage that organization. This could allow an unauthorized administrator to influence how users log into specific organizations.

The Red Hat Product Security team has assessed the severity of this vulnerability as Moderate, given that it requires high-privileged administrative access (manage-identity-providers) to exploit. Successful exploitation allows an attacker to associate identity brokers with organizations they are not authorized to manage, potentially influencing login flows. The vulnerability's root cause is a missing authorization check in the generic identity-provider creation REST endpoint. Red Hat would like to thank Paul Bottinelli (Trail of Bits) for reporting this issue. Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
